Introduction of 50KG Heavy Rail
50kg of heavy rail material has 50 Mn, U71Mn two kinds, length is 12,12.5 meters two kinds, the quality requirements in the production process strictly, in addition to guarantee its chemical composition, also requires testing of mechanical properties, including the drop test and acid corrosion macrostructure examination, etc.
Main Application
In order to meet the needs of railway reload and high speed, in addition to increasingthe single weight of heavy rail,and the comprehensive performance should be improved.Higher toughness, abrasion resistance, crushing resistance and brittle resistance are required.The 50kg weight rail is fully compressive, wear-resistant and tenacity. Therefore, the heavy rail of 50kg is usually laid on the main trunk line of railway transportation.
